Excellent diagnostic service on longstanding problem with my car that I brought in..Competant and efficient work and pricing of multiple things that needed doing on a car that is is somewhat rare and not all that easy to work on. Car and driver were treated with respect. Though the repairs and service took longer than expected. ( problem with a part delivery - not Collins fault) they were very fair in letting us have a courtesy car no charge.for several days. Their communication and customer care skills are excellent. Paid a fair bill for work well done, My old car is running like a top again..I'll be back ;-)
