fender seats

i have a 1995 automobile that needs repairs?
i have a 1995 auto. it is in gr8 condition, all original fixtures, no paint job, never any damage, nothing is wrong with it at all. the thing is, one day my brother decided he wanted to be mr. mechanic. zipes! he put too much, way too muc oil in it, it started to smoke. the oil tank has to be drained completely. otherwise than that, the radio stereo, belts, tires, gears, exaust, wipers, fenders, interior seating and everything else is fine. i love the car! i pray it can be repaired! its a classic and it is a little sports car with lots of pep. he decided to keep the car in his driveway unknown to me. it hasnt been driven for awhile. but it hasnt been started either, or cranked up in several days. i am hoping he did not ruin my car. if anything i will need a jump start, because since it hasnt been started in awhile, it will need a jump. otherwise after draining i assume it should be fine. but if not, i cant part with it. may i have to redo the untire tanks and under the hood if ruined?
Any thing can be repaired, it just depends on how much money you want to spend if it is broken. How long did you drive it before you found out the oil was over serviced? If not to long and you drained the oil and refilled to normal capacity you might be fine but its hard to say without seeing it run.
