Hi,
You could save $110-$120 and do the Poly-rib Belt yourself. Mine cost me $30. It's just as easy as doing the Plugs. You need to remove the engine Firewall and need a 24mm Socket. Takes about 10 min. tops. Use the socket to move the Tensioner Pulley to relieve the tension. Slip old Belt off and thread new Belt on, release tensioner Pulley, button everything back up. Take Wife/GF out to dinner with your new found wealth.

If interested, send me a PM for the procedure...
Happy Motoring!... Jim'99
