On my recent trip to London I was pretty active on the
http://www.imoc.co.uk/ board. One option in the 'CP' was an extensive garage section that let you give detailed information about your car in a nicely organized way. I figured a few of the administers here could take a look at it and maybe adapt something similar to it. I talked to a few administers there about locations and purchase information and they were very nice, helpful people. I'm sure they could give you the HTML or similar for it. Just pitching in my 2 cents.
