I'm looking for advice in maintaining my well kept 2000 Boxster.
In 2003, I bought a 2000 base Boxster with 14,000 miles (manufactured 11/99, 2.7L, MT) from a Porsche dealer in Massachusetts, where I primarily reside. The car now has just under 40,000 miles. So I've only driven it 26,000 miles in 13 years, and I have had no major problems. I had maintenance done by the dealer initially for about 5 years, but then switched to a more local independent mechanic with a good reputation, as the dealer was over an hour's drive each way.
Last year I bought a condo in Naples, FL, and decided to drive the car down and leave it there. My mechanic replaced the engine drive belt as a preventive measure before the drive south, and the car was excellent for the long ride. Other than that, over the years, I've mostly only had routine and timely oil changes, plugs, and filters. I replaced the top and the tires a couple of years ago. The CEL did come on at times about a year ago, but it could not be reliably diagnosed. The mechanic suspected an O2 sensor. But the light since went off and all seems well since. Sometimes I can get a puff of smoke when I start it, especially after it was sitting for an extended period, but this resolves when the car is driven more regularly. I believe I have a good storage protocol for the times the car is idle.
In recent years, the AC has been declining. The mechanic added refrigerant periodically, which worked for perhaps a year at a time. I am due for that at least, if not more at this point, as there is no cold at all now. In Massachusetts, this was less of an issue, but now I want to get that more correctly resolved. The AC seems more noisy than it was previously (up front?), so I imagine there's a leak or other issue.
Outside of the AC problem, the car is operating perfectly as far as I can tell. I drive it about 5 weeks a year while in Florida. It is in excellent cosmetic condition, barely a scratch, and always garaged. I'd like to continue to operate the car in this manner indefinitely for the next several years, and hope to spend increasingly more time (winter) in Florida as time passes. Does anyone have any advice for me as to how I should proceed with this car? It looks and drives like new. I'm not a mechanic. I hear and read about the IMS bearing, the AOS, and other issues. I've not had the brakes or clutch done, but they seem fine. Even the battery is from 2003 and the car starts right up.
So I appreciate any advice moving forward. Should I have some of these things dealt with preemptively, instead of waiting for a more expensive failure? I'd like to bring the car in for maintenance and hope I can find a conscientious and competent mechanic to assist me. Does anyone have any recommendations for a local mechanic and/or the dealer in Naples? Would anyone recommend going to an "AC specialist" type place for that one particular issue over a mechanic or the dealer?
