So I am getting a new car after having vw buy back my Jetta TDI, and the wrx has been what I am really leaning towards. I found a '13 wrx near me on craigslist, and has a hitch on it. First question, are hitches aftermarket, or is it a option strait from Subaru? Also, I have a hobiecat 16' catamaran sail boat, and being to tow it behind this car would be really convenient. The boat and the trailer only weigh at most 300lbs, and from front to back of trailer it is probably 18 or 19 ft long. Is this too much for a WRX? Thanks! Non STI btw.
