Not aware of one, be good if it existed though... as you could prempt and pick up a car that makes you a millionaire. As a general rule of thumb, seems to be cars lose what around 50% - 60% of their original value within the first 3 years.... and the big engined German cars seem to be more susceptible... things like M5's etc lose money hand over fist and are fantastic 2nd hand cars to buy.
1. I have a MK1 Golf cabriolet and wondering if the prices are rising yet. I've only owned it 18 months so not had an interest long enough to really know.
2. Still pondering over an E92 335i. I'm trying to half guess what will happen to them. Wonder if they've settled at their lowest (for a decent one) or if they're still falling. Good ones are still demanding £8k-£12k. I'm sure they were about £35k new?
