I drive a works van Monday to Friday and I know what your saying. You feel that it cost a lot to run the Scooby but on the whole even with repairs for wheel damage and new shockers a second car which I had (£700 pug 406 Diesel, very reliable) its not worth it. Spend the Grand a year you would spend on a second car on the Scooby. I doubt you will cause a grands worth of damage or deprecation every year.
I sit in my van and whish every day that I was in the UK300. You bought the car to drive, enjoy it and when you can no longer afford it sell it, but enjoy every minute of it until then.
