Which car would you rather have...?

Which would you prefer...An 02-05 WRX sedan, or a 1998 Mustang Cobra? Here's the reason. I have the Cobra, it has 80,000 miles on it now, and my 2nd child was just born. Can't fit 2 car seats in the back of the mustang and still use the front passenger seat, so I can't take the whole family anywhere. I also live in Colorado, which means about 5 months of the year I can't even drive the Cobra. I can't afford car payments, so I would have to settle for whatever WRX I could afford for what I could get for the Cobra. Here's the tricky part...I don't WANT to sell the Cobra, but should I do it for my family? In the last year, I've spent $3500 rebuilding the engine, $500 completely replacing most of the brake system, new clutch, fairly new tires...Is it worth it to sell for a WRX where I would have to start over, and would need modifications just to get back to where a stock cobra is? What would you do?
