Hello all new to the world of Subarus. In some major need of advice. Been looking at blob eye WRX wagons for a while (need an estate car for the dogs and something fun) Use my van all week so its just mainly a toy and evening car. Found something perfect, 2004 model but the only issue is high number of previous owners (8) even tho its low'ish mileage (90k) Should alarm bells be ringing because they are, or do you tend to find performance cars such as subarus change hands a bit more because they are deemed as toys, expensive to run/maintain? Also the current owner says he's had the car 6 months, but the HPI check says it last changed hands in March 2015. So hes maybes the 9th owner unregistered... Saying that some of the best cars I've owned have been off some proper dodgy characters! A bit annoying really as everything else is perfect apart from the previous owner niggles. Any advice? Stay clear or worth a look? (its 200 miles away tho)
