Short trip worry?

[kensilver]

I'm using my DB9 more and more for daily short trips of 20 minutes around town. What will happen to the engine eventually, and when? Should I worry?

How many long trips should I do to compensate for the short ones - if at all?

Thanks all, that's what I thought. When I first bought it my son who's a qualified tech thought he felt some slight misfiring that he said was due to not being used enough. In the last 10 months I've put on 3000 miles and there's no hesitation now. But I thought the short trips might be a problem later on, so after reading your replies I went and did a big motorway blast. Well, I feel better anyway!
