The Weber Spirit 500 and 700 series grills were limited production grills. The Weber Spirit 500 series was manufactured from 1995 to 1998 but, to the best of my knowledge, the 700 series was only produced in 1998.
These grills were the bridge between the Genesis 1000-5000 series and the Genesis Silver, Gold and Platinum grills.
The Weber Spirit 500 series replaced the the Weber Genesis Junior and was in turn replaced by the Weber Genesis Silver A.
The Weber Spirit 500 series consisted of the Spirit 500, Spirit 520 and Spirit 530. The parts between the Weber Spirit 500 series grills are completely interchangeable.
The Weber Spirit 500 was a two burner grill with a molded plastic side table. It was primarily available in black but a sandstone and green version were available through Target and LL Bean, respectively.
The Weber Spirit 520 was functionally identical to the Weber Spirit 500. The cosmetic differences were that the side table was constructed of Durawood slats and there was a picture of the Chicago skyline on the front of the grill. The Weber Spirit 520 was also known as the Weber Spirit Skyline. Apologies for the “nual” in the picture..another screen capture from an owner’s manual.
Last up in the Spirit 500 series in the Weber Spirit 530. The Weber Spirit 530 s identical to the Spirit 520 with the exception that is does not have the Chicago skyline on the front of the grill.

The Weber Spirit 700 grill was a three burner that came in three models: Spirit 700, 700 LX and 730.
The Owner’s Manuals for these grills are provided below. I believe the only differences between these three grills are cosmetic issues involving side tables and handles.
