Convertible is the question. Had an older one, not in minn but in va, snow and ice held up ok but would still prefer a semi-rigid covering for storage. If going the storage route any chance it would fit in one of those public storage units for the winter?
Dirt? I didn’t see no dirt. Although, i agree re two different ‘tics’.
one does sound ‘normal’ and the other (longer gap between sounds) sounds ‘normalish’ but dunno, i’d be tempted to sniff around under the hood and then under the chassis in an attempt to chase it down. How’s your oil level?
