Just to add my tuppence worth on the situation...
I know someone who was involved in a accident whilst driving his Mum's car, he was asked to produce the relevant documents (license, insurance cert. to his local police station). He had no worries until he went there and found that his policy did not actually allow him to drive his Mum's car third party. There was a clause in the handbook of terms you get stating that third party cover on other vehicles was only valid over the age of 25. Which is as far I know the same with my policy.
Second, it would be illegal to drive another car as your main car. You can twist and bend whatever your told by your insurance company as much as you like, but if they get a sniff that your driving a far higher risk car on the policy as your main car they'll void your insurance. Insurance companies are not stupid, they will look for every opportunity to void your claim.
Can't understand why you need a `powerful` car. That SEAT has 100,000 miles and is only taxed till March. I bought my 2000 Fiesta for £1000, it had done 53,000 miles and was pretty well looked after. I live out in the sticks and have to use lots of narrow twisty roads with very little opportunity to overtake and still manage to overtake cars without too much bother in my 1.25. It's pretty nimble and very predictable to drive. My insurance in my name with Mum as a named driver is £850 with no NCB.
Just can't understand the reasoning of buying a car you can't afford to run, insuring it third party and then when you do eventually wrap it round a tree... you lose everything
