Hi Brian hows it going?
I'd second JamieP on the loan don't do it! Car loans just are not worth it. You'll never get it back.
As for the Aristo do you relly miss it when it's off the road? As it sounds like it's not been running great for quite a while, you'll probably not miss it.
Cheap cars are great a £1k volvo doesn't owe anything, most common cars loose £2k a year anyway. I'd say go for a nice jap 4x4 keep trusty old volvo. Sell Aristo and Range Rover.
Still where I am I'd never get a nice fast motor, too many t***ers on the road. Maybe when I move back to sunny home!
