I just purchased a 2007 SC430 and searched for days for a good fit car seat and tried various ones out. I finally found a compact carseat called COMBI at Walmart.com and at Amazon.com. COMBI was a perfect fit. I one for my 2 year old and one for my 6 mos old. They are a really good fit and I'm actually comfortable driving and the passenger if comfortable as well... It's still not a long trip arrangement, but still perfect for zipping around town and daycare trips. I'm still excited to have found these perfect light weight and compact carseats. TAX-DIVA
