I'm on the other side of the coin. I say get a beater for work. I had an '84 SVO that was my only driver for 13 years and it had over 200.000 miles on it. And in the end, the frame got tired, the interior was worn, the driver's side seat was toast, parts started failing and in the end it looked like it had 200k on it. Plus, I got used to driving it everyday. I still miss my old car. Then I bought a '96 Cobra in '99 with 32.000 miles, excellent condition. Drove the car to work (40 miles a day both ways) about three years and it accumulated about 98.000 miles before I bought my other car. I noticed things like the plastic parts inside as well as my driver's seat and steering wheel wearing, so now I have replaced most of the stuff with factory parts and have retained the good looks of the car. Plus, when you get a slower car for work, you will really appreciate your Mustang. Also, it may help you lower your insurance premiums. They usually give you a second car discount and tell them that your 'Stang is not used for work duty and you will put less than 7.000 miles/year on it
