If you can, look for classic car insurance (agreed value.. always! & stated yearly mileage) you will also need a daily runabout to qualify:~

I keep my '88 240 outside- plus the '97 V70.. The Riley gets the garage!
As advised above: plenty of wax treatment, worth researching some to identify the hidden areas that need treatment.
Keep it polished to protect the paint work: servicing these cars at home is well within the capabilities of most and not expensive.
Then use it with confidence and plenty of style!
Good Luck.
