Hi Mustang,
The answer to why not take it to another mechanic? Well, I bought it four weeks ago. Prior to buying it I had it at 2-3 mechanics and paid over $300 to get it checked out. I "knew"what repairs I needed and it wasn't too cost prohibitive to buy.
Post buying, I paid a bunch to fix the loose steering I knew about by a different mechanic. It didn't fix the steering. The fix by another mechanic didn't fix the electrical problem I was told it had but didn't. I had to take it to this mechanic to find out it needed a new alternator. So by this time I've had this vehicle at 5 mechanics. Its a pattern when I have a problem, I go from mechanic to mechanic spending lots of money trying to find the problem. I find it really only gets solved once I go online and figure out the problem and tell a mechanic how to fix it. So I'm doing that now to prevent the same trip o round multiple mechanics.
