What you have done there is sell to someone that only cares about profit. If/when it pops up on Veloces it will have an asking price of £6500 minimum, if Veloces go off their normal pricing, even higher than £7000.
The replacement vehicle I bought privately was 3 years old with 9,600 miles on the clock, FSH with every conceivable extra and cost me about £2.5k less than a main dealer price. If I had part-ex'd the Alfa I would have lost another grand. So in my estimation I saved a total of £3.5k plus the sale price of the Alfa, £3.5k, which means that I am £7k better off.
Have you ever spoken to an Alfa dealer like Veloces? They are not your usual second hand car dealers, they are enthusiasts and they do live in the real world. Paul offered me a price based upon an email and some attached photos. When he saw the car in person he stuck to that price and we were both happy.
The car will receive the best attention possible and will go to someone who will appreciate that it is probably as good an example as they will find, plus it comes with a warranty that no-one else could offer privately.
Finally, before buying any Alfa, one should do their homework and preferably Compare The Market. What is better: Racoons, Monkeys or Meerkats? The answer is simples!
Merry Xmas to everyone and Alfa Happy New Year.
