This may sound dumb, last two weekends I have enjoyed a lengthy ride in the Plus 4 (about 80 miles or so). On returning and sliding her into the garage I've noticed a hot sweet smell, like hot candy floss....eminating from the car but difficult to pinpoint where. Never noticed it before last weekend, no performance issues while out in the car, any ideas? I'm worried something is chafing or disintegrating unseen.....
