Maybe Being Petty but...

Just found my SO and I are expecting. Super excited and happy, but thinking about our car. I have a Camaro -- its been my dream car since 16 and I adore it and was so proud! (Still am); worked so hard saving the money for it. But I know good and well toting a baby in the non-existent backseat will be a pain...groceries are bad enough! SO wants to get rid of it for a bigger car, but I want to keep it and get a second vehicle in addition. We can afford another note, but SO just doesn't want to... Oh gosh, am I being selfish?
