history
okay I have had my car since new (mar 2001), a misano totally standard with about 18,000 kms. I have moved house so nowadays it sits under a cover as its quicker to use the bus to get to work. (yes I know its a waste)
problem
I want to buy a new camera lens been wanting one for years - a very expensive one (if you think a grand is expensive then you are just thinking too cheaply

resevations
I don't mind her driving it, but I know she won't take as much care as me as to how and where she drives or parks, so I know it will get scratched and minor bumps or knocked in the car park etc.
solutions
1. we keep both cars and mine gets used like now about 6 weekends a year and I just take the flack for buying the lens for the rest of my life.
2. we sell her car and she uses mine and I get to keep it and wash it at weekends, her argument being that it should be used. (may be easier to get her to agree to mods though)
3. we sell both and buy something that I care less about eg a freelander or base level quattro
I should just add that we really only need one car - as I still have a motorbike or two for my use
suggestions or comments please
