To put it into perspective for you, my wifes seat arosa 1.4 automatic cost 150 quid for cambelt and water water pump.
My subaru r sport wagon gona cost me about 400 quid for belt and pump, that being said I have more car and more fun, maintain it well and the 3/6 month cost isn't to extreme.
If you use aftermarket parts the cost is a lot less, but cant always predict quality, since your not gona do many miles a year running cost should be fairly low.
Your getting what you pay for, nice car reliable and fun, much better than a 1.4 automatic lol
