seals can be baught as a kit and can be replaced with little effort, tedious, but getting it done by somebody else wouldnt be worth it...
respray are dependant on a heap of factors, such as, rust, condition of existing paint... also dependant on what paint you want, harlequin paints being the most expensive, then black and so on. i got quoted $2000 for my RA28 to be repray in the same colour and i did all the body work! $6000 if i wanted them to cut the rust out (theres very little) and get the little dents out...
all this and your cars out of order for about 3-4 weeks...
