I second Damian. Ask for, get and follow-up on past customers experience. If they are unwilling then talk about or have a couple of past customers call you, move on. I pulled out the cluster twice to get the odo-meter side of the cluster fixed at LA/Orange county reputable speedo shops. Ends up the first one was not reputable and did a poor job plus I had to get the BBS (Better Business Bureau) involved to get my item back. Seems as though he wasn't paying his lease and he got locked out. That fix lasted about 2 years and then the same gear 'broke' again. The next time i took it to a higher end shop and this time I got 4 years out of it before it broke again. That was 15 years ago. Now the milage seems to stay the same and I really don't care. Just drive the darn thing.

If I really want to know what a typical month of driving will do then I throw in a gps and track the miles. Of course this is also a good time to see what the mpg is too.

been officially around once but stuck at a low number for 15 years!
