If you are not going to drive it for long, then advice is go for
second-hand cars. The first owner had suffered the frist drops for
you, meaning the super drop in value the moment you get the new
car.
As for monthly, 300 will be for road tax, season parking and
petrol. Are you including your insurance? Which so, another
100-200(young drivers). Meaning you installment for car will goes
about 300-400. You will need to take the full loan period for new
car not exceeding 41k. Since it is OPC, add 17k, you have 58k
budget for a car. Get a car magazine, circle those car that you can
afford. Then study them. I guess looks should filter quite a quite
away. Take your time and slowly work things out, it can be fun.
