Alright mate
I have just spent 2 months searching for my 2nd is200 (my first was an insurance write off) have searched high & low every night on the net for the right car depends how much money you have to the ease of your buy ! I wanted a sport only, black or granite, the black ones are harder to come by, silver ones are plentiful and green ones seem a little cheaper ? I got a nice clean granite one, x reg with sat. nav, 50,000 miles for under 12 k it took some finding and I looked at a few cak ones .
Take your time
The lex dealers are very good , you will get a good car but expect to pay a grand for the priviledge
decide on spec, colour, age and set a max mileage
then be ready cos the good ones and bargains go pretty quick
Good Luck
you wont be dissapointed !!
