The $$$$ you mentioned sound very reasonable.
Could you also please tell us just how many miles you have been driving the Gallardo in those years.
I've learned that number of years of ownership doesn't allways say much.
When I purchased my first NSX back in 2002 I literally drove it everywhere, summer and winter and put on 25,000 miles on it in the first year of ownership (and not easy either :biggrin
Am now on my second NSX and have it this month for exactly one year and have driven 11,000 miles.
Yet, when I see Ferrari's, Lambo's or even the Audi R8 for sale here (in Europe that is), they seem to have been driven for less than 4000 miles a year.
Personally, I think that makes a lot of difference. Having to service you car every 3 months and changing tires every 6 month changes to $$$-picture considerably when compared with a car where you only have 1 service every year and a set of tires every 2-3 years.
