I have done mechanic work for a few providers and a few hobbyist also. Some pay cash and a few have bartered for the work. Depending on the estimate given for the work and an understanding before hand, it can be done. As stated in this thread, money sometimes is tight and the work needs to be done. Just as we research providers they should be able to research if your shop is legit. Just my two cents. Originally Posted by xavierz21I've done mobile mechanic bartering also. Just have to clear what work will be done and what's expected from both sides.
