|
| Bingo.
|
| You can't get away with AI slop in a service oriented for
| wealthy customers.
|
| The day my dealership starts answering me with AI they lose a
| customer 100%.
|
| This solution screams "built by a tech bro with no idea about
| economics and marketing" which is the VC playbook into
| modernizing (and failing) businesses they don't understand.

| OP's brother is by all accounts running a successful boutique

| keiferski wrote:

| NiloCK wrote:

|
| A BMW owner has fussier standards (on average) than a Toyota
| owner. The 'higher touch' a service you're trying to provide,
| the less welcome these interventions will be. If there's a
| distinction between a normal-car garage and a luxury-car
| garage, this probably comes down to some sort of licensing or
| certification from those luxury brands. Seems plausible to me
| that luxury brand X could stipulate things like availability
| of human contact points.

| keiferski wrote:
| This isn't accurate. Lots of types of people own older used

|

| I used to work as a service advisor - or as the article says,
| receptionist. This system will not work as described for several
| reasons.
|
| 1. Unless you have a recent job that matches the exact same
| repair/service, you have incorrectly estimated the cost of the
| repair. In some states, this matters a lot and will cost the shop
| money. Unless your LLM only quotes for labor in sane amounts for
| diagnostic and nothing else, you're only adding noise. This is a
| disservice to the client and the shop owner. The client now has
| an inaccurate quote for work and the shop will get a reputation
| for being inaccurate in quoting work.
|
| 2. Let's say that you manage to get the exact same job twice.
| Your machine now needs to source parts. Parts may have been in
| stock yesterday. The might be out of stock now. If they are in
| stock, you need to retotal the price since prices are dynamic.
| Did you teach the agent how to source parts? What rules does it
| have for sourcing used parts?
|
| 3. New jobs can't be quoted. Even if you taught the machine how
| to calculate book time and margins, it still has to find the
| right parts. If your shop does high end work, you know how much
| of a pain in the ass this is. Also remember that some work
| requires nonobvious parts - like fluids if you need to remove a
| part in the way of your goal.
|
| 4. The only area I see this being useful in is pickup. The shop
| can mark a car as done and the LLM can call to inform the client
| that they can come at a preset, unchanging time to get the
| vehicle. If the vehicle is staying overnight, the LLM can call
| with a progress update.
|
| Finally, I'd like to note that this sort of dev work goes beyond
| hubris. It's dangerous. The more we assume we know without
| verifying, the greater the risk. In this case, the dev is risking
| someone else's livelihood.

| throwaboat wrote:
| Yes. However, an estimate is not a guess.
|
| From the Washington state attorney general's website:
|
| " Estimate: You are entitled to a written price estimate for
| the repairs you have authorized before the work is performed,
| only if you deal face-to-face with the facility and the work
| is expected to cost more than $100. Once you receive an
| estimate, the facility may not charge you more than 10% above
| the estimated costs without your prior approval.
|
| The estimate includes, among other things: the odometer
| reading; a description of the problem or the specific repair
| requested; choice of alternatives for the customer; the
| estimated cost; labor and parts necessary for the specific
| diagnosis/repair requested"
|
| So the LLM builds an estimate. Maybe it's under 10%
| difference when the customer walks through the door.
|
| When it's not, there's a big problem. Yes, this is still
| before work has begun, but now you've wasted the customers
| time. And potentially wasted their money if the vehicle was
| towed in.

|
| I don't see how "estimates" given over the phone by the LLM

| would be strictly before repairs have been authorized, and
| it's obviously not a written estimate. If the client
| requests a written estimate, it would have to come at a
| later time after the human mechanic reviews related costs
| (like specialty parts availability/ship times), or the
| client bringing the machine in for physical inspection by
| the mechanic.
|
| From my understanding of the article, it doesn't sound like
| the LLM is built to fully circumvent a customer phone call
| by the owner/mechanic before approving a job request
| unmanned: It's simply to not let go of a client lead
| because there was no one available to answer the phone,
| without needing to hire a full-time phone receptionist.
|
| It seems highly unlikely a customer is towing their vehicle

| has some context and the ability to sift nonsense requests
| from realistic ones from the logs before calling or writing
| to the customer on their own time with all the expert

| throwaboat wrote:

|
| In most shops, mechanics do not talk to customers.

|
| Regardless, the potential for sticker shock exists if the

| That's why service advisors are trained to only quote for

|
| Finally, in the sales training we got, we were taught to
