In my opinion,If you do a color change and do it right it shouldnt affect the value that much,,,,,Low mileage doesnt always mean the car is worth more..COndition matters also..
You can buy a car with 10,000 orig miles but if it sat in the drive way for ever it prob needs to be completely restored...Ive seen pagodas with 350,000 miles that look better than ones with 50,000 miles..depends on how they have been taken care of..
