What a lovely looking Gen 1 & low miles to boot!
Makes me yearn for my old "Big Red".
Now is it standard or "Ivanised" ?
These pristine Gen 1s must be one of the best bargains to be had at present.
If it was mine I would be looking at replacing brake hoses (if yours are originals which they appear to be in pics) with braided,giving the brake system a full overhaul-new seals/fluid-if no evidence from previous service history.
Check condition of cooling system-hoses/rad/jubilee clips and check all your electrical connectors for integrity/freedom from corrosion.
Also action of F & R suspension.
Having done all this then get out and enjoy that fantastic motor
