When I purchased my 1998 Corvette it had 32,000 miles on it, and when I too k it to my mechanic (who has serviced my cars for years, to a high level of quality), he recommended BG services, and trusting him immensely I had him perform all services. Shortly afterwards my water pump went out and the co mpany paid full replacement costs ($650.00). So, my experience has been a p ositive one.
Read the companies warranty/service plan carefully, as to maintain the warr anty long-term, follow up services need to be carried out at specific inter vals. Yes, they are not inexpensive, but to me it's cheaper than paying out of pocket for repairs on vehicles which are expensive to maintain. I recen tly had all BG services performed on my BMW M3, and knowing repair costs fo r this thing, I now have a high level of comfort that should any mechanical failure occur I will be spared having to take out a second mortgage to get it fixed.
