We've been taking both our Japanese cars to Diablo for a long time, more than a decade. The cars were young when we first used this shop. Tim always takes time to carefully explain what he's found and what our options are. He works with us to come up with the best solution, always considering cost and insisting on safety. He does what he says he'll do, when he say he'll do it for the cost quoted (occasionally less). I've never had a reason to complain. My cars, btw, are now 14 and 18 years old and running great.
