Dear Doctor: I purchased a Cadillac XLR. I am concerned that with all the GM problems that parts will become hard to find. What are your thoughts? Thornell

Dear Thornell: I would not be concerned about parts or service on any GM vehicle -- even discontinued models such as yours. GM is now out of bankruptcy and will recover under its reorganization.

Dear Doctor: I own a 1995 Infiniti J30, dealer serviced with 130,000 miles. Occasionally there is a gasoline smell in the garage. The dealer checked the car and has not been able to find any leaks. Will a different brand or higher octane make a difference? Sal

Dear Sal: Gasoline smells usually come from rotted lines; rot on the top side of the gas tank that cannot be seen on most vehicles until the gas tank is pulled down to inspect. Leaking fuel lines at the fuel injectors when connected with rubber lines and clamps were not uncommon on this engine, as well as a lot of older Nissan vehicles.

Dear Doctor: I own a 1997 Volvo 850 GLT with only 83,000 miles. I am 65 years old and retired and want to buy another car. My limit is $25,000, so a new Volvo is out of the question. What will give me reliability and what's the value of my 1997 model? JJ

Dear JJ: There are many good new vehicles in the $25,000 range. I would also suggest you consider a two- or three-year-old pre-owned Volvo or off-lease. The cost would be in the range you are looking to spend. The value on your Volvo will range from a wholesale $1,800 to a retail of $3,500. The actual trade-in value will vary on the retail dealer price of the car you buy.
