Bearing in mid that the car is mostly fibre glass....probably not.
The only major concern (for me) would be Winter salt on the roads...especially in the UK.
(Not as big a problem here in Ireland but will be if the Councils every get their act together
)
Until I recently built a garage my car spent all its time outdoors including in the bad Winter a couple of years ago where it got down to -19C and plently of snow.
Car was fine till it went to about -13C consistently day to day and then the engine oil (20/50) was just too thick for the car to start. But I'll forgive it for that.
In terms of rot etc. as John says, the car is 40 odd years old......
Plenty of info on this site regarding what to look for.
