I really like 3 and covet one; but I gotta go with 4. The enthusiasm is infectious! Plus, I had no idea International Harvester made anything other than farming equipment!
Gotta vote #1 only because we had some of that ugly Avacado colored appliances. Gak.
Tempted by 4, but 1...our vacation house appliances were all burnt umber and avocado. BLEECCH.
#1 for the horrible avocado - and the fact that nothing in that kitchen matches. It's a nightmare.
