Last year I got myself a nice standard every day RST= it was a great car and I really enjoyed driving it and owning it- until I decided to turn it into a track orientated car.
It became uncomfortable, not nice to drive, noisey etc. Then I smashed it and brought Tims... we'll you know that one.
In this situation you need to look beyond the cost and look at what will make you a happy person- because ultimatly being happy with a wife and Kids is the most important thing.
If the answer is sell it- do so.
If the answer is store it- do it.... I think the last thing you will do to be fair is sort all the issues out.
Best of luck mate- if u brake it I'll have the braided fuel lines tho.
Chin up mate...
