Char-Broil Performance Series Amplifire 4-Burner Gas Grill: price & specs

Re-fetched the official charbroil.com product page for the Performance Series Amplifire 4-Burner Gas Grill (Model # 463341021 — exact model match), whose structured specification table confirmed verbatim: Burner Count 4, Total BTUs 35000 (Main Burner BTUs 25000 + Side Burner BTUs 10000), Primary Cooking Area 420 (Warming Rack Surface Area 130), Ignition Type Electronic ("Electronic ignition for reliable starts"), Side Burner Yes, Grate Material Porcelain Coated Cast Iron, Burner Material Stainless Steel, and both Original and Final price $469.99 (page shows Out of Stock). The source page's marketing blurb states "435-square-inches" and features list says "Porcelain-coated steel grates," but the authoritative structured spec table says 420 sq in primary and Porcelain Coated Cast Iron; the Amazon corroboration agrees (420 + 130 = 550 breakdown; "Cast-iron grates are porcelain-coated"), so the cross-corroborated 420 / cast-iron values were used. fuel=propane is not stated verbatim on the exact-model charbroil page but is explicitly supported by the corroboration Amazon listing for the Amazon-exclusive sibling variant (Model Number 463331422), which states verbatim "Powered by liquid propane gas," "Cart-Style Liquid Propane Infrared Gas Grill," and title "Propane Gas" (also confirming 25,000 BTU main, 10,000 BTU side burner, electronic ignition, Main Burner Count 4). No fetched page states a model or release year, so release date and the release spec are left blank. All 7 recorded spec values, the price, and the null release date verified against fetched text; exact model confirmed.
