You mentioned you wanted light towing, and unfortunately, the Regal does not provide that - no version has any towing as part of its specfication.
If you want a wagon, the one to get that has light towing is the Subaru Outback. About 10% burn oil, but that is about all that goes wrong. This vehicle can tow 2,700 lbs. The late model ones have Apple car play and leather seats (2017 and later).
The Toyota Rav4 can tow up to 3000 lbs depending on configuration. That may be your best bet. It is quite reliable but it does not have Apple Car Play (coming in 2019). These have some concerns as well, but are best in class quality wise.
Honda CRV also can tow up to 1500 lbs, and has Apple Car Play. Also quite reliable, almost what Toyota offers. People are going to mention a few concerns, but they are about the best for used cars in this case.
Mazda CX-5 are more fun to drive but can also tow 2,000 lbs. Also reliable and will fit your need.
Chevy Equinox also will meet your need and can tow up to 3500 lbs. Fairly reliable and will meet your needs again.
Outback is the only wagon I would consider. All those mid-sized SUVs can also meet your need and are fairly reliable. Some will say the Equinox is not reliable - it may not be a Toyota, but it is not bad either. Best of luck.
