I wouldnt bother, just drive it and enjoy it. Seems £1700 wasted when you could buy a full shell in very good condition that dont need painting.
Over the years i have sold many shells that have been in great condition and only charged around £500-1000 depending on what is left on it.
How much extra will your car be worth once its back and you have spent all the time stripping and putting it back together after the paint.
Id rather spend some money making it drive and handle better and spend the change on taking your girlfriend out to dinner. Puts a smile on both your faces instead of loads of agro and headaches putting a motor back together.
Thats my thoughts anyway. I know loads of people will think differently but i have been there and spent loads of money on paint for cars over the years.
Now i will only have something painted that is worth while.
I.e a Rare car. Rare model or something that will hold the extra money you have spent.
