Answer

According to the provisions of Section 7(1) of CGST Act, 2017 all forms of supply of goods or services or both such as sale , transfer, barter, exchange, licence, rental, lease or disposal etc. made for a consideration by a person in furtherance of business would be covered under the term 'Supply' and would be leviable to tax under the GST regime. 
Also as per Schedule II Transfer of business assets
(a) where goods forming part of the assets of a business are transferred or disposed of by or under the directions of the person carrying on the business so as no longer to form part of those assets, whether or not for a consideration, such transfer or disposal is a supply of goods by the person
Therefore sale of car is taxable supply and you will be liable to pay GST.
Yes, You are required to raise tax invoice for the sale of Fixed assets because as per section 31 for each taxable supply tax invoice shall be raised
You will  even raise invoice on the same GSTIN of glass dealer. No  you need not required  separate GSTIN because GST registration is PAN based not activities or business based.
Now the point arises of rate of tax on this supply. 
As you are not availed the ITC on car then you will take the benefit of concessional rate on such supply as per Notification No. 8/2018 -Central Tax (Rate) dt. 25.01.2018 which  provides concession on the rate of tax on old and used motor vehicles under HSN 8703 /87  from 28% to 18%/12% and Vide Notification No. 1/2018-Compensation Cess (Rate)  dt. 25th January, 2018 , compensation cess on all old and used motor vehicles shall be NIL w.e.f 25.01.2018 
The rate(18% /12%) on sale of old car in your case depends upon car  engine capacity, length of motor vehicles or diesel or petrol vehicle.
Further, according to Explanation (i) of Notification No. 8/2018 -Central Tax (Rate) dt. 25.01.2018 for calculating taxable value in case of a registered person who has claimed depreciation under section 32 of the Income-Tax Act,1961(43 of 1961) on the said goods, the value that represents the margin of the supplier shall be the difference between the consideration received for supply of such goods and the depreciated value of such goods on the date of supply, and  where the margin of such supply is negative, it shall be ignored.

 

For example XYZ Ltd Selling  car for Rs 260000 and Depreciated value on that date is 300000 then as per above notification  value of supply(margin) is [260000-300000=(40000)] negative. Therefore XYZ Ltd. is not liable to pay GST on such supply.

 

If the selling price is Rs 350000 then the taxable value of supply (margin) is [350000-300000=50000], XYZ Ltd. is required to pay GST on Rs 50000 @ 18%/12% as the case may be.

You will show this kind of Supply in returns  in the same  place where other taxable supplies are shown.  But only when in the end of Financial  year you are calculating your annual  sale turnover then this kind of supply shall be subtracted from aggregate of supplies shown in the returns for the purpose of Reconciliation.
