I dumped my E430 to get my X5... yes they are very different animals... however, My 430 was my 5th and final benz I will ever own...... never again. Build quality is down.... and customer service does not exist. Ask me about the $1000 blower motor for the climate control, (that is the part cost alone, labor to install is more) or the $600 window switch that failed @ 51K miles, motormounts that failed @ 58K, ball joints at 61K and the list goes on...
