As said in previous posts not a lot go's wrong.Just look for lexus full service history suppoted by invoices for the work ,if not phone garage that has done work and double check.cambelt is around £400 so make sure that is done at 60,000m .for the sort of money you have you can get a sport model ,they look a lot better .as for the two tone cars especialy the white resale will be hard if you do not like it ,check it is not an import as in my opinion most two tones are .i personaly do not like the two tone ones apart from the black over grey .
