dont bother, just wait until you can insure a 172,
but for arguments sake
engine + box £6-700
wishbones £30
Driveshafts £150 (for good ones)
Shocks and springs all round £200
Brakes £50
Hubs £50
new discs/pads/ball joints £100
exhaust system £200
getting all the stuff delivered wont be easy either
and this is assuming you have an engine crane and all the mechanical knowledge to fit it!
and bobs your uncle! youve spent C£1500 on your conversion,
and youre still left with an old clio with bog standard interior, standard bodykit and no resale value!!
and insuring it at 19 will be an absolute joke!!
hence why everyone says its completely pointless!! 172's go for the same money and half the ball ache!!
IF you can find a crashed 172 with a load of body damage but a mint engine for C£500 then you could be on to a winner, but still a massive ball ache!
